Upload your MP4 video. PDF.to pulls the audio track out, encodes it to DTS, and gives you a DTS-only download. The video stream is discarded.
Will the audio in the DTS match the original MP4 quality?
+
If the source audio is already in a codec compatible with DTS, we stream-copy without re-encoding — bit-identical to the original. Otherwise we re-encode at 192 kbps by default for near-transparent quality.
What bitrate is the DTS output?
+
192 kbps privzeto. Options panel razkriva 96, 128, 192, 256, in 320 kbps – izberite višje za glasbo, nižje za glas.
Can I extract only part of the MP4 as DTS?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes DTS.
Does the converter handle MP4 files with multiple audio tracks?
+
Yes. If your MP4 has several language or commentary tracks, you can pick which one(s) to extract as DTS in the options panel.
Will the DTS output have the same sample rate as the source?
+
Da, privzeto. Ne vzorčujemo, razen če ga izrecno zahtevate. 48 kHz je shranjeno iz filmskih virov, 44.1 kHz iz glasbenih virov.
Is the MP4 to DTS extraction free?
+
Yes, within the free size limit. PRO supports much larger MP4 files and parallel batch extraction.
Does PDF.to read or store my MP4 content?
+
No. The MP4 video and the DTS audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple MP4 files?
+
Yes — drop a folder of MP4 videos and you will get a ZIP of DTS files back, one per source video.
Will the DTS preserve tags and metadata?
+
Title, artist, and album tags are populated from the MP4 container metadata when available. You can edit them after extraction with our audio-tag tool.
Ali pretvornik deluje na streaming video URL-je?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the MP4 legally first, then upload it for DTS extraction.
Why is the DTS file much smaller than the MP4 video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the DTS, which is why it can drop from gigabytes to a few megabytes.
